Application filed October 15, 1907. Serial No. 397,511.

To all whom it may concern:

Be it known that l, Gus'rxv K001i, a citizen of the United States, residing at St. Cloud, in the county of Stcarns and State of Minnesota, have invented certain new and useful improvements in Vehicle-Springs, of which the following is a specification.

My invention relates to springs for vehicles and especially to springs used on motor vehicles and has for its object the provision of means for taking up the jar incident to passing over unevcnncsscs in the road, said means consisting of mounting plung in air-tight casings so that the reciprocai 11 of the plungers is utilized to pump air into a suitable reservoir from which it may be drawn to be used in inflating the tires of the vehicle as well as to operate the horn or for other purposes.

The construction, operation and advantages of my invention will be illustrated. in the accompanying drawings in which- Figure 1 is a side view partly in section of one of my iin rcved springs, Fig. 2, a top lan-view, anr Fig. 3, a cross section onthe inc :c-w of Fig. l.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

1 indicates the axle of a vehicle on which is secured the hanger 2 b means, of U- shaped clips 3 or other prei errcd construction. Hanger 2 is provided with sockets 4 to receive one end of the bow springs 5, 6 indicating set screws to secure the ends of the springs in said sockets. The other ends of springs 5 are formed with eye-loops '7 to receive ins 8 secured in clips 9 on the under side 0 the body hanger 10. It will be understood from this construction that should one of the s rings 5 be broken it can be quickly repiace Without loss of time incidental to replacing broken springs as at present con structed.

11 indicates a cap piece secured to the top of body hanger 10 having air ti ht sockets 12 therein forming the cylinders 0 air pumps to receive the pistons 13 on the upper ends of rods 14 extending upwardly from axle hanger 2.

15 indicates a coil spring surrounding each of the rods 14 and bearing against axle hanger 2 and body hanger 10. 16 indicates a sprin in each socket 12 interposed between the on of the piston and the end of the cylinder 12, the function of said springs 15 and l 16 being to cushion the jar incident to passing over rough places in the road.

"17 ind icatcs valves loading to cylinders 12 and 18 valved pipe connect ions leading from said sockets and 19 pipes secured to said connections and leading to a suitable storage tank, not shown, the purpose of this construction being to utilize the reciprocation of the pistons 13 to store air to be used in inilating the tires of the vehicle, or sounding the horn alarm, etc.

- 20 indicates springs secured to cars 21 on plate 21 and to eycbolts 22 secured in the side sill 23 oi the vehicle that rests on body hanger 10. The purpose of said springs 20 being to restrain the rebound of the body after passing over an obstruction. The plate 21 is secured to or formed integral with hanger 2 at one end and has its other end scoured to axle 1 by means of clip 24.

Having thus described my invention what i claim is 1. In a vehicle s ring, in combination with springs connecting said han ers, a cap secured to the body hanger aving sockets therein, rods secured to the axle hanger and having their ends inserted in said sockets, coil springs inclosing said rods and having their ends engaging said hangers, and coil springs in said sockets and engaging the ends of said rods, substantially as shown and described.

2. In a vehicle spring, in combination with the axle, the axle hanger, the body hanger, and bow s vrings connecting said hangers, a cap securec to the body hanger having sockets therein, rods secured to the axle hanger and having their ends inserted in said sockets, coil springs inclosing said rods and hav ing their ends engaging said. hangers, coil s rings in said sockets and engaging the ends or said rods, the vehicle body sill secured to said body hanger, and, springs secured to the axle and sill, substantially as shown and d cscribed.

3. In a vehicle spring, in combination with and bow springs connecting said hangers, a cav secured to the body hanger having airtig it sockets therein forming cylinders, rods secured to the axle hanger, istons mounted in said cylinders and sccurei' to said rods, inlet and exhaust valves connected with said cylinders, means to convey the air comthe axle hanger, t is body hanger, and bowthe axle, the axle hanger, the body hanger,"

re'ssed in said cylinders to store it, the veidicle body sill secured to saidbody hanger, and springs secured to the axle and sill, substantially as shown and described.

4. In a vehicle s ring, in combination with the axle, the axle anger, the body hanger,

and bow springs connecting said hangers, a ca secured to the body hanger having airtig t sockets therein forming cylinders, rods secured tothe axle hanger, istons mounted in said cylinders and secure to said rods, ,inlet and exhaust valves connected with said cylinders, means to convey the air compressed in said cylinders to store it, coil springs inclosing said piston rods and engag ing said hangers, the vehicle body sill secured to said body hanger, and s rings secured to the axle and sill, substantia y as shown and described.

let and exhaust valves connected with said cylinders, means to convey ,the air com-- I pressed in said cylinders to store it, coil springs inclosing said piston rods. and enga in said hangers, other coil springs in the cy in ers and bearing against the ends of the hanger, clips secured to said body hanger, the

free ends of said springs formed with loops,

'pins secured through said loops and the 011 s on the body hanger, a cap secured to t e body hanger having air tight sockets therein formin air pump cylinders, rodssecured to the a e hanger, pistons mounted in said cylinders and secured to said rods, inlet and exhaust valves connected with said cylinders,

- means to convey the air compressed in said cylinders to store it, coil springs inclosing said piston rods and engagin said hangers, other coil springs in the cy inders and bearing against the ends of the istons, the vehicle body sill secured to said body hanger,. and springs secured to the axle and sill, substantlally as shown and described.

In testimony whereof I hereto afiix my signature in the presence of two witnesses. w l GUSTAV KOCH.
